Xojo Syntax Support

VS Code Extension Xojo Language

Upgrade the Xojo workflow inside VS Code

A VS Code extension for the Xojo programming language. It adds syntax highlighting and outline views through DocumentSymbolProvider for .xojo_code, .xojo_window, .xojo_menu, and .xojo_script files. On macOS it can also integrate with Xojo so F5 reloads and runs the project.

What's new · v0.9.0 · 2025/10/4

  • Added outline support for the menu hierarchy in .xojo_menu files.
  • Implemented parseXojoMenuSymbols to parse the nested structure Begin Menu → Begin DesktopMenuItem.
  • Assigned a SymbolKind per menu item type (DesktopMenuItem, DesktopQuitMenuItem, DesktopApplicationMenuItem, etc.).
  • Reads the Text attribute and shows it as the detail for each menu item.
  • Represents separators (Text = "-") as SymbolKind.Null.
  • Verified menu hierarchy display with the MainMenuBar.xojo_menu sample.

0.8.0

  • Implemented multi-level handling for #tag Events blocks so events of nested controls are correctly parented.
  • Extended parseCommonTagBlocks to support hierarchical array-style controlsByName.
  • Automatically builds control paths (parent chains) and prefers the nearest scope when duplicate control names exist.
  • Manages control info in {name, path, symbol} form inside parseXojoWindowSymbols.
  • Verified hierarchical events using the settingWindow.xojo_window sample's #tag Events blocks.

0.7.0

  • Enhanced .xojo_window control hierarchy detection to display parent-child relationships based on the InitialParent attribute.
  • Improved nesting so children appear properly under container controls like DesktopTabPanel.
  • Added the settingWindow.xojo_window sample to provide a test environment for hierarchical control structures.

0.6.0

  • Expanded .xojo_code outline to support top-level objects other than Class (Module / Interface / Structure / Enum).
  • Implemented parseXojoObjectSymbols to automatically apply suitable grouping per object type.
  • Added sample files: SampleModule.xojo_code, SampleInterface.xojo_code, SampleStructure.xojo_code, SampleEnum.xojo_code.

0.5.0

  • Added Xojo Reload and Run feature (macOS only).
  • Added F5 execution via a debug provider.

0.1.0

  • Initial release: minimal highlighting (comments / strings / numbers / keywords / types).

Make Xojo code shine in VS Code.

Highlighting, outlines, and one-click run support for day-to-day Xojo development.

Syntax highlighting

Highlights comments (' / REM / // / #), strings, numbers, control keywords, declaration keywords, primitive types, and function names for both declarations and calls.

Outline view for .xojo_code

Builds outline hierarchies such as Class, Module, Interface, Structure, and Enum with grouped Methods, Properties, Events, and Constants.

Outline view for .xojo_window

Shows Window, Controls, Events, Methods, Properties, and MenuHandlers in outline form, with accurate parent-child detection from InitialParent.

Outline view for .xojo_menu

Recursively parses menu hierarchies and renders them in the outline so complex menu structures remain easy to understand.

Xojo integration on macOS

Provides macOS-only Xojo integration. F5 can trigger Xojo Reload and Run, and launch.json can be generated automatically for quick project startup from VS Code.

Supported file types

Supports .xojo_code, .xojo_script, .xojo_window, and .xojo_menu files. Generic code files can also expose flat lists of Sub, Function, Method, Event, and Delegate symbols.
